Description

A kind of whitening cosmetic and preparation method thereof

technical field

The invention belongs to the field of cosmetics, and in particular relates to a whitening and lightening cosmetic and a preparation method thereof.

Background technique

When the skin is irradiated by ultraviolet rays, melanin, which determines the color of the skin, is produced and released, causing hyperpigmentation such as melasma, freckles, and spots, all of which have adverse effects on beauty. The synthesis process of melanin is as follows: tyrosinase in cells acts on tyrosine to form dopaquinone, thereby producing melanin. Therefore, in order to prevent darkening of the skin, researchers have devoted themselves to research on inhibiting the synthesis of melanin, thereby reducing the synthesis of melanin itself.

At present, most raw materials in the field of cosmetics achieve the purpose of whitening and lightening spots through a single mechanism or a combination of several mechanisms, but the functional effects of these raw materials used in cosmetics are not satisfactory. On the one hand, the raw materials themselves have defects, and on the other hand On the one hand, it is difficult to add to the formulation system, which brings great difficulties to the formulation, or is easy to change color, or is too irritating to the skin, resulting in a high allergy rate, or has no effect. Arbutin, oxidized linoleic acid, heavy metals, kojic acid, hydroquinone, etc. are often added to traditional freckle products.
